Title: Sapphire r9 270 can't go over intensity = 13 Post by: Forexperiments on February 05, 2014, 10:13:18 PM Hi, I had a system with a Radeon 5970. It worked fine at i=18, no hw errors.
Now, I changed the 5970 with two brand new sapphire r9 270, i get lots of hw errors if i>13. Why is this? The PSU is not powerful enough? Title: Re: Sapphire r9 270 can't go over intensity = 13 Post by: satsumi on February 05, 2014, 10:28:51 PM -g 1 -w 256
Higher -g will cause hardware errors at any intensity above 13. Title: Re: Sapphire r9 270 can't go over intensity = 13 Post by: CMD7790 on February 07, 2014, 01:13:19 AM you could try either -I 17 -g 1 --thread-concurrency 12000 or -I 19 -g 1 -w 256 --thread-concurrency 16384.
that should give you a good base line. you probably need to tweak the settings a bit though. |
